LASTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 588,568, dated August24, 1897.

Application filed July 29, 1896. Serial No. 600,890. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD FRANKLIN GRANDY, a citizen of the UnitedStates, residpertains to make and use the same.

My invention relates to improvements in lasting-machines, and moreparticularly toimprovements in that type of lasting machines whichembody in their structure a flexible last band or clamp which embracesthe heel or too portion of the upper upon the last and holds it firmlyin position during the lasting operation.

The present invention consists of improvements in the form andarrangement of the last band or clamp and its actuating mechanism,whereby said clamp or band is made to con form more accurately to shapeof the toe or heel of thelast whether the same be pointed or round.

The present invention further consists of connections between themechanisms which actuate the clamp or band and the wipers, whereby themovement of the wiper-actuating mechanism effects the operation of thelast clamp or band.

The present invention further consists of certain other improvements inthe form and arrangement of parts, hereinafter more specifically setforth and claimed.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a plan view of a toe-lasting head with the top plate removedand a portion of one of the lasting-plates or wipers and the actuatinghandle or lever. broken away, the lasting plates or wipers being drawnback and the last clamp or band open.. Fig. 2 is a side elevation oftheitoe-lasting head, partially insection, showing its connection withthe supporting-carriage. Fig. 8v is a plan viewsi'milarto Fig 1, showingthe .parts in the positions which they occupy when the lasting plates orwipers have been moved forward and the last band or clamp is in closecon;

tact with the end of thelast. Fig. 4 is a detail plan view, reduced, ofa portion of the head, showing more clearly the construction of theactuating mechanism for the last band or clamp. Figs. 5, 6, and 7 showdetails of the mechanism for actuating the last band or clamp, whichwill be hereinafter more fully described.

As shown in the drawings, the present invention is illustrated inconnection with the machine disclosed in Letters Patent of theUnited'Stated granted'to me January 7, 1896, No. 552,834; but it is notrestricted to its application thereto, as it may be employed withlasting-machines of any other suitable or preferred form.

In the drawings the slide 1, pivoted head 2, adjusting-screws 4, bearing5, sleeve 6, segmental worm-gear 7, worm 8, lasting-plates 10, and themechanism for actuating the lasting-plates may be, and conveniently are,of-

the same construction as corresponding parts in the machine abovementioned, except as will be hereinafter noted.

Before proceeding to a detailed description of my improved last band orclamp I desire" to state that while I have illustrated it in connectionwith toe-lasting devices the use is in' no wise restricted thereto, butit is equally applicable for use in connection with heellas'tingdevices, and I consider such application thereof clearly within thescope of my invention. 1

In the drawings, A represents the last band or clamp, formed of leatheror any suitable flexible material,so as to readily conform to the end ofthe last.

B represents a carrier or frame, which may conveniently consist of thecross-bar b, to the ends of which are pivoted the arms b, havingattheir-free ends the upturned blocks 11*, to which are secured the endsof the last band or clamp. At the rear of bar I) of thecarrier B are theprojecting guide -bars b which,'as shown, may be of substantiallyrectangular shape'in cross-section, which are fitted to slide insuitable guideways a, formed in the plate 61, which is projected fromthe sleeve 6" and which sustains the lasting plates "or-wipers.

The above-described arrangement is such that a forward-and-backwardmovement of the carrier or frame B will carry the last band or clamptoward or from the last.

In order to insure a close contact between the last band or clamp at itscentral portion and the toe of the last, I provide a spring-actuatedfollower or carrier (J, to which the last band or clamp may be attached,as at c, to a suitable block or projection formed thereon by anysuitable means.

Carrier 0, as shown, comprises the plate 0 which preferably extendsnearly across the recess formed in the front of plate 61 andat its rearis provided with suitable guide-rods c, which are fitted to slide inbearings 0 formed in plate 61. In these bearings are placed suitablesprings a which rest at one end against the bottom of the bearings andat the other end against the guide-rods 0, the arrangement being suchthat upon a forward motion of carrier B the follower or carrier C isforced forward by the springs 0 carrying with it the central portion ofthe last band or clamp and forcing it in close contact with the end ofthe last.

For the purpose of reciprocating the frame 13 and thus moving the lastband or clamp toward and from the last substantially simultaneously withthe forward-and-backward movement of the lasting plates or wipers I haveprovided suitable connections'between the lever or handle 19, whichoperates the lasting devices, and the frame or carrier 13, whichactuates the last band or clamp.

Pivoted at d to the plate 61 is the lever D, in which is fitted a stud dupon the bar I) of the frame or carrier B, the arrangement being suchthat a swinging movement of lever D upon its pivot d will, through theslot-andstud connection thereofwith the frame or carrier B, cause acorresponding movement of the said frame and the last clamp or band.Lever D at its free end is connected by a universal coupling (Z to a rod(1 said rod passing through an eye formed in a lug d", see ured to orformed on the lever 19, a nut or head d on the rod forming a suitablestop to engage the lug (1 whereby a backward movement of lever 19 willalso cause a backward movement of the rod (Z and the lever D, causing abackward movement of the frame B and the last band or clamp.

It is often desirable to give a further forward and closing movement ofthe lasting plates or wipers after the last clamp or band has movedforward a sufficient distance to clamp the end of the last, and toenable this to be done I have provided a yielding connection betweenlever 19 and the rod (1 This yielding connection may comprise, as shown,a suitable spring d surrounding said rod and bearing at one end againstthe lug d and the other against an adjusting nut or collar (i upon saidrod.

In order that the last band or clamp may be held open when retracted, asshown in Fig. 1, I have provided suitable springs e, i

one end of which is secured, as by screws 6', to the plate 61 and theother end to the swinging arms 1;, whereby said arms will be swungoutwardly on their pivots when the parts are retracted, thus causing thelast clamp or band to assume substantially the position shown in Fig. 1.

In order to retract the carrier 0 against the tension of springs c andthus retract the central portion of the last band or clamp, the frame Bis provided with the forwardly-projecting arms b upon the ends of whichare the lugs or stops N, which engage the frame or carrier 0 and causeit to be retracted when the frame or carrier B is drawn back. In orderthat the last band or clamp may be caused to closely embrace the end ofthe last and to smooth out the upper and tightly clamp the same allaround the toe or heel, I have provided the flat springs 6 which aresecured by one end to the blocks N, from which they extend toward thecentral portion of the clamp or band in close contact therewith, thefree ends being adjacent to the point of con nection c of the clamp orband to the frame or carrier 0.

In the operation of the machine of the drawings, the upper being drawnonto the last, the last is jacked in the usual manner. The 1ever 1%) isthen moved forward and through suitable connections, as fully shown anddescribed in said patent, causes a forward and closing movement of thelasting plates or wipers 10. Substantially simultaneously with thisforward movement of the lasting devices the lever 19, through itsconnection with frame B, moves said frame forward, the springs a at thesame time causing a forward movement of the frame 0, which brings thecentral portion of the clamp or band into contact with the upper at theend of the last. The continued forward movement of frame B will carryforward the ends of the clamp or band A, which will cause the arms I) toswing on their pivots, (spring e yielding,) and thus the clamp or bandis carried around and brought into close contact with the upper on thelast, tightly clamping the same and preventing it from moving duringthelasting op eration.

In some kinds of work it is advantageous to have the clamp or band closeon the upper before the closing of the lasting plates or wipers, and inother kinds of work it is of advantage to have the last clamp or bandand the wipers come in contact with the upper at substantially the sametime, and it will be noted in connection with the construction hereinshown and described that by means of the adjustable nut or collar (i therelative time of closing of the clamp or band and the lasting devicesmay be regulated.

Having thus described my invention and its mode of operation, I claim asnovel and desire to secure .by Letters Patent of the United States- 1.In a lasting-machine the combination with the lasting plates or wipers,of a last band or clamp, and connected mechanisms for actuating thelasting plates or Wipers and for closing the last band or clamp aroundthe upper on the last, substantially as described.

2. In a lasting-machine the combination of lasting plates or wipers, alast band or clamp, mechanism for actuating the lasting plates orwipers, mechanism for closing the band or clamp, and a yieldingconnection between said actuating mechanisms, substantially asdescribed.

3. In a lasting-machine the combination with a last band or clamp, of aspring-actuated followerarranged to advance the central portion of saidband or clamp, substantially as described.

4. In a lasting-machine the combination with'a last band or clamp, ofsuitable supports for the ends thereof, and an independent yieldingsupport for the central portion of the band or clamp around the upper onthe last, substantially as described.

5. In a lasting-machine the combination with a last band or clamp, ofsuitable supports for the ends thereof, an independentlymovable supportfor the central portion of said band or clamp and means for advancin gand retracting said central support, substantiallyas described.

6. In. a lasting-machine the combination with a last band or clamp, ofsuitable sup ports for the ends thereof, and springs secured to saidsupports andprojecting along said band or clamp, substantially asdescribed.

7. In a lasting-machine the combination of suitable lasting plates orwipers, a last band or clamp, connected mechanisms for actuating theplates or wipers, and to close the band or clamp around the upper on thelast, and means to adjust the actuating mechanisms to adjust therelative movements of the lasting plates or wipers and the last band orclamp, substantially as described.

8. In a lasting-machine the combination with a last band or clamp, ofspring-controlled supports for the ends thereof, and a yielding supportfor its central portion, substantially as described.
